focusPercent not firing for merged cells

Archived

Hi,

I’m using a MarkupGrid and for each MarkupGrid XML Component I observe focusPercent to apply an effect as focus is gained on each item. This works great until I merge some cells. For any merged cells the focusPercent is not fired at all.

Say I have 2 columns and 2 rows, and 3 content items.

I set item 1 to take up to cells as follows:

x=0
y=0
w=1
h=2

And I set Item 2:

x=1
y=0
w=1
h=1

And I set Item 3:

x=1
y=1
w=1
h=1

Now focusPercent will only fire on items 2 and 3. When I set the focus to item 1 I get no focusPercent events for that item at all.

Any idea why?

Thanks,

Ryan

Hi,

I’m still struggling to find a solution to this one. To me, it seems like a fundamental bug to the grid focus logic. But maybe I’m missing something. Therefore, I have created a sample Channel to highlight the bug which can be found here:

grid-bug-focus-sample

If you run the sample, you’ll see it never calls showFocus for cell index 0. I.e. the observer for the focusPercent field is not fired for the item 0 which merges 2 cells. However, it is fired as expected for the other cells.

This is causing a major stumbling block to using the Grid.

Thanks,

Ryan

I have the same problem( I use merging cells for hiding empty ones in the first row. Maybe there is another way to do it? I also tried to set numColumns the number of non-empty elements, but it leads to a cutoff of the poster image. Width change does not produce positive results.

for hiding cells I would first try setting the cell to “visible = false” or “opacity = 0”

Adjusting the config.brs and creating a blank cell it now works. (also in main.brs (for i=0 to 3 step 1)

function getGridTemplate() as Object
if not m.gridTemplate = invalid
return m.gridTemplate
end if
m.gridTemplate = [
{
id: 0,
x: 0,
y: 0,
w: 1,
h: 1
},
{
id: 1,
x: 1,
y: 0,
w: 1,
h: 1
},
{
id: 2,
x: 1,
y: 1,
w: 1,
h: 1
},
{
id: 3,
x: 0,
y: 1,
w: 0,
h: 0
}
]

return m.gridTemplate
end function

and you can see in the pic all 3 cells are firing

I can’t do it because of the cell m.MarkupGrid.content.getChild(i) is invalid.
